SNOW-PLOW.

SPECIFICATION forming part of Letters Patent No. 446,286, dated February 10, 1891. Application filed August l, 1890. Serialrllo. 360,651. (No model.)

To @ZZ whom, 2125 may concern.-

Be it known that 1, ARTHUR GAEDINER, of Terrace, in the county of Box Elder and 'lerritory of Utah, have invented a new and usefullmprovementin Snow-Flows, of which the following is a full,clear, and exact description.

My invention relates to an in'iproveinent in snow-plows, and'has for its object to provide a device of simple and durable construction, capable of working eiectually in heavydrifts or deep and solidly-packed snow-banks; and a further object of the invention is to provide a device whereby the snow, as the plow is advanced, maybe thrown to either side of the track as the operator may desire.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures ot' reference indica-te corresponding parts in all the views.

Figure 1 is a front elevationof the snowplow. Fig. 2 is a vertical section on line 2 2 of Fig. 3. Fig. 3 is a vertical section through the plow,taken at a right angle to thesection illustrated in Fig. 2, illustrating the application of motive power to the plow; and Fig. 4 is a plan view of the plow.

The body of the plow consists of a shell 10, the major portion of which is circular, the said shell being open at the front and closed at its rear. The frontof the shell is made flaring to asubstantially rectangular contour, as illustrated at 1l in Fig. 1, the object of which is to enable the plow to cover a large area and to concentrate the gathered snow into the Smaller or cylindrical portion of the casing. The front or flaring end of the casing is provided with a series of horizontallylocated partitions 12, the outer side surfaces of which partitions are given a knife-edge or made practically sharp. lVithin each coinpartinent formed by the said partitions a blade 13 is horizontally pivoted, and each of the blades is twisted longitudinally. The trunnions of the blades extend through the Haring sides of the casing, and each trunnion has secured thereon, preferably, a sprocketwheel 14. The sprocket-wheels are inclosed at the front by a suitable housing 15.

At the upper end of the circular section or body of the casing an opening 16 is formed, which opening is inclosed by a hood 17, open at its top and flared at its ends in opposite directions, the upper edge of the said hood being inclined downward from the center in opposite directions, and at the central upper portion of the hood a cover or lid 18 is centrally hinged, which cover is capable of closing one side of the hood, as is illustrated in ,Fig 2; but two covers or lids may be provided, if in practice it is found desirable. y

l/Vithin the circular body portion of the cas ing aconveyer-wheel A is held to revolve, the shaft of which wheel extends rearward through an openin g in the back of the casing. 'lhe wheel comprises a rear solid disk 20, secured to or formed integral with a hub 19, which hub is attached to the shaft, and a forward skeleton disk or circular frame 21, also attached to a. hub 19, which disk is spaced some distance from the rear diskand is provided with a series of openings 22, the forward disk 2l being composed of a peripheral ring and a series of ribs or spokes radiating' from the ring and the hub, as shown in Fig. 2. Some distance from the center of the wheel between the front and rear disks a series of pintles 23 is secured, the said pintles being concentrically arranged with reference to the hub, and upon each pintle the inner end of a feathering-paddle 24 is hingedtlie said paddles being adapted to engage with rods 25, also located between the front and back disks of the wheel, the paddles being pivoted between the rods and the rods being located near the periphery of the Wheel. Thus in carrying the snow each paddle rests at an inclination against one of the rods 25, as shown in Fig. 2, and if the wheel is revolved to the left the paddles contact. with the right-hand rods and throw the snow through the lefthand opening of the hood 17, which portion of the hood is uncovered, and vice versa.

The plow above described is attached in any suitable or approved manner to one end of a suitably-mounted truck 26, and upon said truck an engine or engines 27 of any suitable design are located, connected with a drive- IOC shaft 29, 'lhe drive-shaft is provided with bevel-gears 29, splined thereon, the said gears being adapted to mesh with a gear 29 upon the wheel-shaft and to be acted upon bya sh ift- -ing-lever 30. The drive-shaft has secured at or near each extremity a sprocket-wheel 31, and the said sprocket-wheels are connected bybelts 32 with the sprocket-wheels 14 of the twisted blades.

In op'eration it is evident that as the plow is pushed forward the knife-edge partitions l2 serve to cut or slice the snow horizontally, and the revolving twisted blades convey the snow inward through the openings in the front disk of the conveyer-wheel, and snow thus conveyed into the wheel lodges upon the paddles thereof, and the centrifugal action of the wheel as the paddles approach the opening 1G of the casing causes the snow to leave the conveyer-wheel and fly out at the side of the plow in the direction in which the paddles are inclined.

I desire it to be distinctly understood that I do not confine myself to the exact mechanism illustrated for communicatingmovement to the drive-shaft and to the twisted blades, asA equivalent mechanism maybe substituted without departing from the spirit of the invention.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. In va snow-plow, the combination, with a casing having one open daring outer end, of horizont al partitions located in the said flaring end, and twisted blades jonrnaled in the cas ing between the said partitions, as and for the purpose specilied.

2. In a snow-plow, the combination, with a casing provided with one open outwardlyiiaring end, an exit-opening at the top, and partitions horizontally located in the flaring end ot' the casing, of twisted blades pivoted between the partitions, and a conveyer-wheel held to revolve at the rear of the partitions and twisted blades, the said wheel being provided with openings in its outer face, and a series of hinged paddles, as and for the purpose specified.

In a snowplow, the combination, with a circular casing having one end enlarged and flaring and provided in its top with a hood, the ends of which hood are inclined, and a lid hinged upon said hood, of' partitions horizon tally locatedl in the Haring ends of the casing, the outeret'lges whereof are sharp, twisted blades pivoted between the partitions, a conveyer-wheel held to revolve at the rear of the partitions and twisted blades, provided With openings in its outer face, stop-rods concentricallyarranged near the periphery, and pad-A dles hinged between the faces of the wheel between the hub thereof and the stop-rods, t-he Lipper ends of which paddles are adapted to engage with the stop-rods, and a driving mechanism for the con veyer-wh eel and blades, substantially as described.
